Described planet gear speed increaser is provided with the disc type internally toothed annulus, it is inboard to be fixed on the left bearing frame, front wheel driving shaft is provided with flywheel, the flywheel cylindrical is shaped with tooth rest, three planetary wheels are housed on the tooth rest, and the front wheel hub left end is shaped with sun gear, sun gear and three planetary wheel engagements, three planetary wheels and disc type internally toothed annulus intermesh, and the front wheel hub inner circle is provided with left and right sides bearing.
Described seat adjuster is provided with and slides up and down guide rail, upper slide rail upper end is connected with the backrest type vehicle seat, the lower end is provided with the L-type guide rail, the guide rail lower end is provided with some positioning grooves, lower slider guide rail upper end is provided with guide-track groove, and front end is provided with position fixing handle, and the position fixing handle rear end is provided with connecting rod and locating clamp plate, retracing spring is housed on the connecting rod, and locating clamp plate is stuck in one of them positioning groove of slide rail.
Theory of machines of the present invention is: when the people rides over when holding the port right side on the backrest type vehicle seat and holding up bar to turn left, fan type gear right-hand turning behind the front fan type gear driven, back wheels of vehicle is followed right-hand turning, relative and front-wheel is left-handed turning, otherwise, hold when holding up the bar turning clockwise about turning to, the back wheels of vehicle left-handed turning, relatively and front-wheel be right-hand turning.
When the foot-operated left and right sides pedal of people and connecting lever driving front-wheel, at first be that three planetary wheels of flywheel drive turn around internally toothed annulus and sun gear forward on the axle drive shaft, drive forward speedup rotation of sun gear in the time of three planetary wheel rotations, large front-wheel is followed forward speedup rotation, when the people is foot-operated when stopping operating, flywheel skids, and large front-wheel slides forward idle running.
When the human hand upwards lifted position fixing handle, locating clamp plate left the slide rail positioning groove, and pulling vehicle seat can move forward and backward, the suitable rear release handle in seat, and locating clamp plate relies on the elastic force automatic clamping of retracing spring in the some positioning grooves of upper slide rail.
Select little trailing wheel, reserve sufficient space, left and right sides bumper can be movable in a big way, obtains comfortable damping effect, selects large front-wheel can improve crossing ability and the driveability of uneven road surface.
The present invention is reasonable in design, novel structure, and its advantage is: 1. the antagonistic force that people's leg is exerted oneself by bike the time is not limited by human bady gravitational in the vehicle seat rear backrest, obvious labor-saving effect is arranged.2.. in the time of by bike people's leg forward, health recedes, the human body crotch is not oppressed by vehicle seat, and health is had health-care effect, vehicle seat can move forward and backward, applicable different crowd, vehicle seat is short, center of gravity is low, safety performance is good.3. the benefit without chain before driving rear steering is to turn to drive to be independent of each other, and turns to flexible driving comfortable, and good damping effect is abandoned the tired brain that chain brings simultaneously.4. wheel base of the present invention is short, and volume is little.
Further specify below in conjunction with accompanying drawing.
